How a roof survey works in Harlesden
Most houses have more than one roof to look at. Rear extensions, dormers, porches and garages often have flat roofs in felt, EPDM rubber, GRP or asphalt. They’re included alongside the main roof, including signs of standing water, splits and tired upstands. A flat roof normally wears out sooner than a pitched one, so they deserve a close look. A felt roof often lasts around 15 to 20 years, and GRP up to about 30. Typical surveys look at cracked or blistered flat roof coverings and slipped, cracked or missing slates and tiles, across natural slate, lead flashings and flat roofs.
London has Victorian and Edwardian terraces in almost every borough, often with slate roofs, chimney stacks shared with neighbours and gutters hidden behind parapets. Good slates can last over a hundred years, yet the nails frequently give out first and let slates slip. In Harlesden, as across London, that is why a roof needs a proper look rather than a glance from the street. Lead flashings and shared chimney stacks on these houses need a proper look too.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later.

Signs you need a roof survey in Harlesden
Slates and tiles frequently outlast the fixings that hold them. ‘Nail fatigue’ is common on slate roofs: the nails rust and the slates slide. On tiled roofs, battens and pegs can rot, letting tiles move.
A survey makes sense if you’ve noticed:
- Condensation or damp timbers in the loft
- Slipped, cracked or missing slates and tiles
- Cracked mortar along the ridge
- Flashings that have come away from the wall
If you run a business near London Designer Outlet, a dated report on the roof is useful for planning and for any lease discussions.

Getting in touch
There is no need for technical words. It’s enough to let us know:
- Pictures from the garden or a window, if you have them
- Where the property is, with the postcode
- Whether there’s a loft hatch, a shared roof or tricky access
- The kind of building and roof involved
Unsure which package suits your roof? It is easiest to ring 07833 053749 or use the contact form and describe the roof and what’s worrying you. We’ll explain the options and the price.
What this survey cannot tell you
It helps to know what a survey will not do before booking:
- What’s under the slates, tiles or felt
- An exact number of years the roof has left
- The condition of the rest of the building (that’s a RICS home survey)

Questions from Harlesden
Is drone flying allowed in Harlesden?
Typically it comes down to two things: the airspace at the address and the weather. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. High wind or heavy rain also stops a small drone flying, and the rest of the survey does not depend on the drone.
Can parking be tricky for a visit in Harlesden?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. That way the visit can be planned around it.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We can only inspect what we are given access to.
Can you survey at the weekend?
We carry out surveys seven days a week. To arrange a date, ring 07833 053749 or send us an email.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What does a roof survey cost?
Roof survey starts from £150, including VAT. We confirm the price for your roof before booking, and it depends on the roof’s size, access and the package you choose. For a price, call 07833 053749 or send us an email.
Do you test for asbestos?
No. Asbestos testing is not part of our service. Where materials might contain it, we say so in the report so a specialist asbestos surveyor can check before any work.
Why get it checked now?
If you’re planning to sell, a roof survey can help you prepare. You’ll know what a buyer’s survey might pick up. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, with VAT included. We can help you choose the package that fits what you need to know.

How the survey works
After the inspection, everything we found is written up in a report with photos, sent to you by email. As for time on site, most surveys take roughly 1–2 hours at a typical home, though large, tall or awkward roofs take more time. For a visit in Harlesden, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start with the property details and any concerns.
- We agree a date, including weekends if that suits you.
- Outside, we inspect from the ground, windows and other safe vantage points, and from the roof where safe.
- We then look in the loft for damp, staining and the condition of the underlay.
- You receive the report with photos and recommendations, prioritised by urgency.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Buyers: confirm access with the estate agent or seller
- Let us know where we can park nearby

A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the visit with that in mind.
